По формуле механической мощности 
, где F - действующая сила (Н), 
- скорость (м/с). В данном случае действующая сила (F), есть сила тяжести 
т.е.
, где m - масса тела (кг), g - ускорение свободного падения (g = 9,8 м/с² ≈ 10 м/с²). Подставив в формулу мощности 
выражаем находимую массу тела (груза): 
. В системе СИ: 1 кВт = 1000 Вт. Подставляем численные данные и вычисляем: 
Работу определяем по формуле 
, где N - мощность (Вт), t - промежуток времени (с). Посдставляем численные данные и вычисляем: 
Дж.
